I got a 2009 Nissan Sentra and I'm finally getting all of my equip installed, just ran into one problem! On the antenna adapter, which is Metra part 40-NI12, I'm not sure about the blue wire and where it goes. I just hooked the normal antenna plug into the aftermarket radio, but my reception was horrible. It says the blue wire is a power booster for reception, so do I connect it with the red power wire or the remote blue wire on radio install kit? Thanks
